IMPROVEMENT IN GRAIN-METERS.

Specification forming part of Letters Patent No. 218,216, dated August5, 1879; application filed April 19, 1879.

To all whom it may concern:

Be it known that I, GEORSEE W. BARNARD, of Economy,in the county ofWayne and State of Indiana, have invented a new and valuable Improvementin Automatic Grain-Measures; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of mygrain-measure. Fig. 2 is avertical sectional view of the same. Fig. 3 isa perspective detail view; and Fig. 4 is a detail view, showing a planof a portion of the measure and the T-headed journal.

This invention relates to automatic grainmeasures and it consists in theimprovements in the construction of the same hereinafter fullydescribed, and particularly pointed out in the claims.

A is the side of the measuring apparatus, which is preferably made of aquadrantal form. B is the partition, preferably so located that thecompartments will contain an equal amount of grain. D are the journalswhich support the measuring apparatus, and are located some distanceabove the bottom of the same. E is the bottom piece, which receives thejournals D, and is provided with an opening, e. The upper part of thisbottom piece is cut concave upon a circle, 0 of the same radii of thecircle of the bottom of the measuring apparatus. This circle isdescribed from the journals D as centers.

The bottoms of both compartments of the measuring apparatus are open, asshown at b, and the parts so constructed and arranged that as the radialline b is vertical the openin g in the bottom piece will partially openthe measures, and as the apparatus is oscillated to the right the rightmeasure will be opened, and when oscillated .to the left the leftmeasure will be opened.

B is a curbing formed about the opening of G is a wicket or swingingportion of the partition B, hung on the journals 0 c. The journal 0 hasa T-formed arm, 0 located in a horizontal position, as the wicket is inline with the partition.

D D are levers pivoted to the upright E. F F are arms connecting thelevers D and D with the measuring apparatus.

G G are strokers held in position by the frame G which is attached tothe standard E, and are so located and constructed that they will carryany surplus grain from the one measure into the other as the measureoscillates beneath them.

When the measure I) is being filled by the flowing grain, the arm F andthe lever D are resting upon the T-headed journal of the wicket, and thejoint formed by the rod F and arm D tends slightly downward. Asthesurplus grain pushes against the wicket it causes it to swing, whichtrips the levers, and the Weight of the grain in the filled measure 12oscillates the apparatus.

The arms D D are provided with the flanges dfiwhich permit of but aslight downward inclination in the joint, which insures an easy trip bythe T-headed journal of the wicket.

The operation of my invention is as follows: One of the measures beingset under flowing grain, as soon as it is filled the surplus, pressingagainst the wicket 0, causes one of the arms of the T-headed journal tounlock or trip the joint of the levers and arm connecting it to themeasuring device, and the weight of the grain oscillates the device. Asthe overfull measure swings under the strokes, the surplus is carriedinto the empty measure, and the opposite measure locked in position.

The weight of the wicket is sufficient to return and retain it in itsposition; but the T-head may be actuated by passing under the piece b,(shown in Fig. 3,)and it may be retained somewhat in its place byfrictional contact.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an automatic grain-measure, the vessel A, constructed asdescribed, and provided with the vertical partition B, extending fromthe bottom to quite near the top of said vessel A, in combination withthe fixed bottom E, having discharge 0, the wicket O, swinging upon theT-headed journal G and the arms D D and F F pivoted to the vessel A andto the upright E, as and for the purposes set forth.

2. In an automatic grain-measure, the comright and the oscillatingmeasuring device, bination of the strokers G G, secured to theconstructed and operating as and for thepurpost E by the frame (3*, withthe measuringposes set forth. vessel A, constructed as described, as andfor In testimony that I claim the above 1 have the purpose set forth.hereunto subscribed my name in the presence 3.
